2 Claims.

,The present inventionrelates to cellular cartons and has particular reference to an improvement in cartons of the type adapted to form a carrier for eggs or similar fragile articles.

5 Cartons of the oellulartype are largely used for transporting eggs and the like, and in such use the cartons are 'often subjected to jarring or to similar shocks which have a tendency to cause breakage of the eggs. It has been suggested to provide the bottom of egg cartons with cushioning means, and it is standard practice to form, the bottomof the carton in the shape of an inverted V, whereby the egg is suspended above a surface upon which the carton is placed.

The present invention'pertains to improvements in cartons of this'general type and has a principal object in the provision of. aflat bot: tom carton having an inner bottom section of inverted v-shape. An. additional object is to provide a carton having an inner or false bottom of greater width than the outer bottom and formed of the same piece of material as the main body of the carton. A further object is the provision of improved means for interlocking a longitudinal partition with a bottom section.

These and other objects will be-apparent from a consideration of the following illustrative and so -.explanative description and by reference to the accompanying drawing, in which Fig. 1 is a top-view of a carton constructed in accordance with my invention and having its cover in opened position;

Fig. 2 is a cross sectional view of the carton shown in Fig. 1 taken along line 2--2, the cover of the carton being'in closed position;

Fig. 3 is a cross sectional view taken along line 3-3 of Fig.1; and y 40 Fig. 4 is a plan view of the blank from which the carton shown in Fig. 1 is constructed. The carton shown in the drawing is made from a blank of paper or other suitable material cut and scored to form in the order named a cover-locking strip -1, atop 2, an outer rear wall 3, a flat'outerbottom section 4, a front wall 5, cross partitions 6 and inner rear walls '7 and an inner or false bottom section 8 of greatered. .Inproduction. it is desirable to fold thesection.

blank over along a scoring between the cross partitions 6 and the front wall 5 and to form a reverse fold along the scoring between the inner-rear wall 7 and the inner bottom' section 8. Glue is applied to the outer face of the inner 0 rear wall 7 and the blank is folded over along the scoring between the rear wall 3 and the outer bottom section, thereby forming a collapsed or flattened carton. In this condition, the outer bottom section 4 and the wall 5 are in substan- 5:

tially a horizontal plane whereby the inner bot-' tom section 8, which is wider than the outer bottom section, can extend beyond the latter to partially overlie the front wall 5.

. To erect the carton, pressure is applied along the scoring between the cross partitions and the front wall and along the scoring between the rear wall and the bottom section whereby the walls are distended into substantially rectangular cross section.

When the walls of the carton have been pressed into substantially rectangular cross section, or in other words, into erect position, a separate longitudinal partition 9 is pressed downwardly against the substantially horizonso tal cross partitions, thereby rotating the latter into vertical position. The cross partition is provided with a plurality of upwardly extending slots 10 which engage the cross partitions below.

.longitudinal partition. These feet are adapted to be thrust through correspondingopenings 14 which are arranged along the central portion of the false bottom a. The feet extend into these openings as the longitudinal partition is thrust downwardly against the cross partitions. When the longitudinal partition is extended into its final position in engagement with the cross partitions the feet 12 extend to the outer bottom The longitudinal partition is then pushed in the direction toward which the hooks or shoulders 13 point, thereby engaging the latter with the underside of the false bottom adjacent the openings 14 therein. This forms an interlock which prevents the longitudinal partition from being removed by upward movement.

The false bottonris free to move within the body of the carton and in accordance with my invention the outer bottom section is provided with openings 16, whereby the lingers of the opno erator may be thrust upwardly through the bottom and into contact with the false bottom, whereby the position of the latter when the longitudinal partition is thrust downwardly thereagainst may be controlled to some extent.

It has been found in practice that by pressing the false bottomupwardly during the insertion of the longitudinal partition the latter operation is considerably facilitated.

An objection to thefuse of longitudinal partiis that after insertion the longitudinal partitions are apt to beaccidentally withdrawn by movement of the longitudinal partition in the direction opposite that toward which the hooks 13 point. As shown in the drawing, I provide a downward extension 17 on the end of the longitudinal partition toward which the 'shoulderslB point and this extension eng s a slot 18 in the false bottom. It will be seen that engagement of this projection with the false bottom 'will prevent or retard retraction of the longituthe outer bottom of the carton and has its outer ends pressedagainst the front and rearsurface uponwhich the carton is positioned and eggs packed in thistype of carton may be dropped from a considerable height without the percentage of breakagewhich is characteristic of cartons known heretofore.

Various changes in the above described embodiment of -my invention will occur to those skilled in the art and such modifications as come within the spirit of my invention are intended to be included in the appended claims. tions of this type in cartons known heretofore I claim: 1. A carton of thetype described, comprisinga single blank cut, scored and folded to form front and rear walls, a flat bottom section, cross of said first named bottom section, said bottom section being folded upwardly in its central portion and suspended to a longitudinal partition.

2. A carton of the type described, comprising .front and rear'walls; a bottom section,'transverse partitions, an inner bottom section folded upwardly along its central portion in inverted V- shape, and; a longitudinalw'partition engaging said cross partitions to maintain the same in erect position, said. longitudinal partition having feet extending through openings insaid inner bottom section and shoul'd'ers engaging the under surface of 'said bottom section to main-- tain the same in suspended condition.
